Rejecting a promise with an object gives a blank failure

[jakecraige]

If a promise is rejected with a normal javascript object the test still fails, but with a blank message. This confused me for the longest time.. It would be great if we could have it at least JSON.stringify the object or alert the user that they should return an Error object like it does if you resolve with a string.

Test case to reproduce plus show current behavior using RSVP promise library:

var RSVP = require('rsvp');

it('gives helpful message when rejected with string', function() {
  return RSVP.reject('an error message');
});
// => Error: the string "an error message" was thrown, throw an Error :) ... stack

it('gives helpful message when rejected with error', function() {
  return RSVP.reject(new Error('an error message'));
});
// => Error: an error message ... stack

it('gives blank message and no stack when rejected with object', function() {
  return RSVP.reject({});
});
// => nothing
